11 Claims.

The present invention relates to an indicating means and magazineejector for nlm handling apparatus of the magazine type and moreparticularly to a combination o! the indicating means and ejectorarranged so that a nlm magazine may be displaced with respect to itsmagazine chamber only when the indicating means is in a predeterminedposition.

While many types of indicating means and magazine electors areindividually well known and while footage indicators have previouslybeen combined with certain parts of a camera. it has never before beenproposed to combine an indieating means and a magazine ejector so thatthe ejector may be operated only in a preselected position ot theindicating means.

The primary object of the present invention is the provision oi acombination including a maga.- zine ejector and an indicating meanswhich are relatively arranged so that the ejector is operative only whenthe indicating means is in a predetermined position.

A further object of the invention is the combination of an indicatingmeans, magazine. ejector, and co-operating parts thereon so that themagazine ejector is inoperative until a graduated member of theindicating means has been moved to a preselected position.

Another object of Vthe invention is the provision in the casing for amagazine type ofl nlm handling apparatus of a panel on which theindicating means and finger member of the ejecting means are located,said indicating and electing means being arranged so that the electingmeans can be operated only when the indicating means is in apredetermined position, and the cover for said casing enclosing saidpanel.

Other and further objects of the invention will be suggested to thoseskilled in the art by the description which follows. A

The above and other objects oi' the invention are embodied in a hlmhandling apparatus of the magazine type and comprising in combination acasing providing a magazine chamber and having a panel adjacent thereto.an indicating means on said panel and movable to various positions forindicating an operating condition of the apparatus, an electing meansfor displacing a illm magazine with respect to said chamber, including alinger member available at said panel and arranged with respect to saidindicating means to be operative only when said indicating means is in apredetermined position. and a cover for said casing. for enclosing saidmagazine chamber, and for covering said panel to render inaccessible thefinger member of said electing means but provided with an openingthrough which said indieating means may be observed.

Reference is hereby made to the accompanying drawing wherein similarreference characters designate similar elements and wherein:

Fig. 1 is a side elevation ci a magazine camera having an indicatingmeans inl accordance with the invention.

Fig. 2 is also a side elevation of a magazine camera with the coverremoved to illustrate the graduated member o! the indicating means andthe nnger member oi the ejecting means.

Fig. 3 is a fragmentary transverse cross sec tion of the indicating andelecting means to enlarged scale and taken on the line 3 3 of Fig. 2.

Fig. 4 is a detail plan view of the support for the indicating andelecting means.

While the present disclosure of the invention is related to a magazinecamera and to the footage indicator thereof, it is to be understood thatthe ejecting means may be combined with any type of indicating meanswhich designates an operating condition of the apparatus and suchcombi-,

nation may be advantageously employed on any illm handling apparatus ofthe magazine type.

In the illustrated embodiment oi' the invention. the nlm handlingapparatus comprises a casing Il providing a magazine chamber il andhaving a panel i2. An objective assembly i3 is appropriately attached tocasing lil, such as on the iront wall thereof. A cover il may be removedfrom the casing i0 for access to the interior of the camera. see Fig. 2,and in closed position is iastened to the casing ill by any conventionalmeans. such as locks or a hinge and latch. not shown.

A mechanism plate i5 extends longitudinally of the casing i0 and formsone wall oi the magazine chamber il. A supporting block i3 is mountedupon mechanism plate i5 and carries the indicating means and ejectingmeans of the invention.

The indicating means may indicate any operating condition of theapparatus, such as illzn footage, tension in the spring motor, nlmadvancing speed, etc., but has been shown herein for purposes ofillustration as a footage indicator. Such a footage indicator .may be ofconventional ionn as shown and may comprise a spindle il rotatablymounted in supporting block i6, a ratchet wheel iii on one end o!spindle Il and spaced from mechanism plate I8 by a washer il, and agraduatedrmemher 20 which is fastened to the other end of spindle il bya pin 2i. Said graduated member 20 carries an annular ring oi serrations 22 and a circle oi footage graduations 23 accompanied byappropriate numerals. As shown in Figs. 2 and i, these numerals rangefrom 0" to 253' The graduated member 2 also carries a peripheral rim ilwhich is provided with a notch 25.

The indicating means may be advanced as indicated by the dotted lines inFig. 2 or may be directly geared to the operating mechanism o! 'inmagazine chamber I 1 the indicating means and 424 to'prevent electingmovement of means.

the apparatus. For purposes oi illustration, advancement of theindicating means may be accomplished by an advancing pawl 2B mounted atone end on a bracket 21 which also carries a holding pawl 28. Said pawls2a and 2a are in engagement with the teeth of ratchet wheel I U and pawl2B is intermittently actuated by a pin 29 on spring motor casing I0 fortooth by tooth advancement of ratchet wheel I8 and the grad uaied member20, retrograde movement of said ratchet wheel i8 and graduated memberbeing prevented by the holding pawl 2B.

The electing means may also be constructed in several ways as known inthe art. A preferred form ci the electing means is shown herein andcomprises an ejector arm 3i, intermediately piv oted to supporting blockI8 by a pin 32. and a finger member 33 having a shaft 34 slidable insupporting block i6. Said ejector arm 3| has a projection 35 on one endthereof and movable into the magazine chamber il as indicated by thedot-dash lines in Fig. 3, while the other end of ejector arm 3l has anarcuate portion 8B which is engaged by a collar 31 fastened to the lowerend of shaft 34 by a pin 3d. Supporting block i8 is provided with arecess 39 surrounding the upper end of shaft 3d and in which is locateda coil spring 40 which encircles shaft 84 and normally holds the fingermember 3S of the electing means in non-electing position. Said fingermember 33 also carries a depending pin 4l which in normal position ofsaid finger member 23 is above and over the peripheral rim it ofgraduated member 29.

The nlm magazine 42 is held in position withi by a spring member 43which is mounted on block is by screws and which has a free end 43' forresiliently engaging a wall of the film magazine 42. The panel l2 isattached to supporting block I@ by a pair of screws 45 and has inclinedoverhanging portions 4I which assist insertion of the film magazine 42into ,the magazine chamber il. Said panel l2 carries an index mark 1 forregistering with the footage graduations 23 on member 20 and said panelI2 is provided with an opening 4s into which the finger member may bemoved.

As before mentioned, the casing cover i4 in its closed position rendersthe electing means inaccessible and also covers the indicating meansexcept that a window 49 is provided in cover I4 and is located so thatthe index mark 41 on panel I2 and a portion of the footage Ygraduations22 may be observed.

The operation of the combination between the indicating means andelecting means will now be However. when the graduated member 20 ismoved to re-set the footage indicator and return the 25 graduation tothe index mark 41, the notch 25 is opposite the depending pin 4|, seeFig. 4, and the finger member Il may be depressed sufiiciently-so thatthe projection 35 on ejector arm 2| moves into the magazine cham ber iland displaces or elects the nlm magazine 42 from said magazine chamberIi. Thus the operator is compelled to re-set the foot age indicatorbefore the electing operation and must prepare the mechanism for theproper reception of another nlm magazine before the rst film magazinecan be ejected. Such compulsory resetting of the indicating means isparticularly useful in connection with a footage indicator on a magazinecamera when only part of a film magazine has been used because theoperator is reminded to record the film footage which has been run sothat no iilm will be wasted when the magazine is replaced in thecamera..

Many other variations of the invention are possible particularly in thearrangement of the co-operating parts, such as the notch 2E inperipheral rim 24 and the depending pin 4I. so that the ejector can beoperated only when the indicating means is in a predetermined position.

Thenotch and pin shown herein are only illustrative and the scope of theinvention is defined by the claims which follow.
